So, we can use part of the GPU to show pretty pictures, and the remainder, say "half", to say, triple FG framerates? ;-) > Are there any decent books about those Navier-Stokes equations and how ..chk these: http://download.nvidia.com/developer/SDK/Individual_Samples/DEMOS\OpenGL\src\gpgpu_fluid\docs\GPU_Gems_Fluids_Chapter.pdf (Yeah, those back-slashes worked in Konqueror!!! 8o)) http://www.gpgpu.org/cgi-bin/blosxom.cgi/Miscellaneous/Books/ http://www.gpgpu.org/cgi-bin/blosxom.cgi/Miscellaneous/Courses/ http://www.gpgpu.org/cgi-bin/blosxom.cgi/Miscellaneous/ http://download.nvidia.com/developer/SDK/Individual_Samples/samples.html#gpgpu_fluid http://www.strangebunny.com/techdemo_stokes.php (arrrgh bummer, should have been done in OpenGL) http://www.eet.com/in_focus/silicon_engineering/showArticle.jhtml?articleID=55300900 http://www.eet.com/showArticle.jhtml?articleID=55300904 ..and you might wanna compare Microsofts take with the other guys: http://www.cs.unc.edu/Events/Conferences/GP2/program.shtml ;-) > to implement them in C or java? ..nonono, FG is C++ and will likely remain so for all sortsa good reasons I was buried under when I asked "Why not C like in the kernel?", an extensive discussion of the wisdom of writing Java code can be found over at http://Groklaw.net/, hints on "follow the money", also points towards Redmond and Lindon, Utah. -- ..med vennlig hilsen = with Kind Regards from Arnt... ;-) ...with a number of polar bear hunters in his ancestry... Scenarios always come in sets of three: best case, worst case, and just in case. _______________________________________________ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
